We've made a change to how the Ranger class feature "Favored Enemy" is implemented on D&D Beyond. This has been done to resolve an issue where the feature wasn't functioning correctly.
All of your Favored Enemies will now display correctly on your character sheet.
Additionally, the OCF (Optional Class Feature), presented in the Tasha's Cauldron of Everything sourcebook, "Favored Foe" was unable to function correctly, due to the way Favored Enemy had been implemented. This change also resolved that issue.
IMPACT ON YOUR RANGER CHARACTER(S)
1st-5th level.
You will need to reselect the additional language that is associated with your Favored Enemy.
6th+ level.
As well as reselecting the additional language associated with your 1st level pick of Favored Enemy, you will need to reselect the favored enemy and associated language granted at 6th level and 14th level (if relevant).

WHY HAS THIS HAPPENED?

Since the early days of D&D Beyond, the dev teams have worked hard to build tools that allow us to model all of the content in the Dungeons & Dragons game. There have been limitations to those tools however, especially earlier on in beta, when the core classes were built.
One of the more frequent issues reported to us over the lifetime of D&D Beyond is, "My Ranger character levelled up to 6th, selected their new Favored Enemy and now I can't see my 1st level pick on my character sheet."
When resolving issues, we have always stuck to a principle of being 100% non-destructive to characters, meaning that we won't implement a fix, if doing so would break someone's character in any way. We have always felt this was important - that our users need to be able to trust that their characters are safe with us.
With this Ranger issue, we spotted an opportunity to resolve the problem, using the more up-to-date tools, but with a small cost - having to reselect some of the options for that feature. We believe that this cost was worthwhile, to resolve the issue, as previously players of Ranger characters couldn't see the options that had been selected anyway.
WHAT ABOUT FIXING OTHER CLASSES/FEATURES?
Our intention and commitment remains that your characters are safe on D&D Beyond. This does not mean that we're going to be regularly making changes that invalidate your current character choices. However we felt the positives of this update far outweighed the negatives for this change. We hope we gave enough warning before the change that people were ready.
Depending on the feedback from the community on this issue resolution, we may take a look at other issues that could be resolved for a similar impact. Please let us know how you feel!

My gloomstalker thanks you lol
Thank you for your hard work and dedication!
A profile-wide copy-paste with history would be wonderful
I’m using Favored Foe from Tasha’s and I’m getting this error on my Character sheet: “The first time on each of your turns that you hit the favored enemy and deal damage to it, including when you mark it, you can increase that damage by scalevalue - No level scale data available.” Any ideas as to what this means or why I’m getting it, or better yet, how to fix it?
Me too.
More than happy to make reselections etc, if it means we get an improved experience or more features! Please just point out any steps we need to take, as you’ve done today :)
I like this change, and I hope they fix the bug soon that prevents choosing Primal Companion as a feature! :)
All about this small cost for fixes! Please bring on more!
Thank you - this was helpful. I appreciate especially you clarifying what brought this change about.
Now I know exactly how many people actually play Rangers lol I'm not alone!
What about fixing the problem with the Eldritch Knight and weapon bonding?
Ahh wish we’d known this was coming.. I’m really glad for the fix, but wish we could have had some kind of heads up as I have quite a few ranger characters and now trying to remember the language choices especially is a bit of a pain (particularly when they’re ones that my characters don’t get to use a lot!)
Excellent work, keep improving, keep changing, keep growing. Each of these little fixes makes the experience overall better for the player. Keep it up
Thank you. Favored Enemy works. However the Favored Foe replacement still has this error message on the character sheet: scalevalue - No level scale data available.
The notification banner worked really well I think for communicating that there was an update.
I would much rather have correct functionality and occasionally have to re-pick a few things; as opposed to incorrect functionality.
Dark mode?
This looks fun yaaaa
Great job guys, small changes by us for a far better experience overall is absolutely on the cards for my groups <3
COOL
Yes! Please fix things. Reselecting options is a very small price to pay for better fuctionality.
